WATER-METER.

SPECIFICATION forming part of Letters Patent No. 229,187, dated June 22, 1880.

Application filed February 24, 1880.

To all whom it may concern Be it known that I, RICHARD J. ROGERS, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new and useful or Improved Water-Meter, which invention is fully set forth in the following specification, reference being had to the accompanying drawin gs.

My invention relates to that class of devices by which is measured the amount of water that passes a given point in the conduit through which it flows and the invention consists in a disk or other suitable body arranged to revolve upon its center, and which is formed or provided with four ormore radial cylindrical chambers having fitted therein suitable plungers connected in diametric pairs, and arranged to slide freely, but closely, in such chambers, and

so constructed and arranged relatively to in-,

let and outlet ports connecting with the waterconduit that, as each of such plungers is, by the rotation of the disk, brought coincident with the inlet-port, the plunger will be forced outward by the water-pressure, and its chamberthereby filled, thus raising its antipodal plunger, and so expelling the water then in its chamber through the outlet-port. A stop device is so arranged as to arrest the rotation of the carrying-disk while the chambers successively fill, and so that when each is filled the added weight of the water therein and such extended plunger will renew such rotation to the extent of bringing the succeeding arm to such stop. 5

Figure 1 is a rear elevation of my invention. Fig. 2 is a front elevation thereof. Fig. 3 is a section as taken on line 3 2, Fig. 1, and through the axis of a pair of the plungers, and showing the inlet and outlet ports. Fig. 4 is a detached view, taken in section on the same line asFig. 3, but showingtheinlet and outletports as passing through the journal on which the disk revolves.

' Fig. 5 is a detached view, showing the upper part of the supporting-standard in elevation and its journal in transverse or vertical section as taken on a line passing through the axis of the plungers, and showing a modification of the inlet and outlet ports. Fig. 6 is a back view 'of my invention, but showing a modification of the means of insuring the filling and discharging the cylinders.

In these views, (i represents the vertical standard or support, which is formed or provid ed with journal I), on which is mounted the revolving disk 0, provided with the four cylindrical chambers d, radially and equidistantly arranged around the disk. The plungers e fit closely, butslide freely, in these chambers, and are each rigidly connected to their respective antipodes by the slides f, which cross each other, as shown in Figs. 2,3, 6, and may have guides upon the back of the disk, as shown at g g, Figs. 2 and 6.

To the inlet-passage h in standard a the supply-pipe is to be connected, and passages z' in disk 0 are so positioned relatively to its center that as they pass the passage h it will be axially coincident therewith, as shown in Fig. 3. The outlet passage j, which also passes through the standard, connects with a passage, 41, through disk 0, in the'same manner as in the case of the inlet-passage.

A short pin, Z, is inserted transversely in plungers e, and at such distance from their inner ends that when the plungers are retractedthe contact of this pin with the periphery of the disk will arrest the plunger before its inner end has reached the bottom of its chamber, (see upper plunger in Fig. 3,) and so that the plunger will not obstruct the flow of water through inlet-passage i in the disk.

A stop, m, is secured to the standard or its base, and by the successive contact of plungers c therewith it arrests the rotation as each. such plunger encounters it.

The practical operation of my meter is described as follows: Let us suppose it in operation, and that plunger 6, which is extended by its chamber being filled with water, has just been arrested by stop m. At that point the inlet-passage i in the disk would be coincident with inlet-passage h in the standard, and the plunger 6 from the stop, and the rotation will 7 be repeated.

It will be apparent that by means of the size of the cylinders and length of stroke of the plungers a standard measure of wateras one or more gallonsmay be delivered by each. plunger when retracted, and that by attaching an automatic indicator to the meter to show the number of revolutions the exact quantity delivered may be thereby correctly determined.

In Fig. 4 the passages h and j are shown as extending within the body of journal I) to the axial line of the cylinders. In Fig. 6 the plungers are shown with small rollers n mounted at their outer ends, while an incline, 0, is so arranged that as the rollers are brought in contact with and mount to its summit the water in the cylinders will be expelled thereby, and 'at'the same time the upper cylinder =will be-filled, as before described, in which case an uninterrupted or continuous rotation is secured, whereby the rotative force of the device may be economized as a motor.

When the plungers are extended by an incline, as described and shown, the passages h j are extended in a circumferential line out through the shell of arbor b, as shown in Fig.

5, in order that the water may be entering atv h and passing out at j, while the disk rotates sufficiently for the roller 12 to mount incline 0;; and if the outlet and inlet passages were ar-. ranged as shown in Fig. 3, then, if the incline: 0 were used, a circumferential groove would be extended from such passages in the inner face of the standard a, in order to allow the com munication with passages i to be kept up while the rollers a mountedthe incline.

What I claim as myinvention is 1. In aiwater-me'tenthe radially-chambered disk or body 0, mounted upon standard a, and arranged to revolve in a vertical plane, and provided with plungers 0, connected together iii-antipodal pairs, with passages 71 communicating with chambers d in said disk, and the inlet and outlet passages h j in the supportingstandard, arranged coincident with the circumferential path of passages 41, and a stop or "incline to act upon said plungers and insure .thelineal reciprocation thereof when antipodal passages 'i are coincident with passages h j in said standard, substantially as specified.

' 2. In a water-meter having the standard a and chambered disk '0 arranged to revolve thereon in a vertical:plane,xand with their respective coinciding water-passages, the combination therewith-of four sliding plungers antipodally connected and arranged to slide in pairs in the chambers in said disk, whereby a preponderating weight at one sideis-effected, causing the rotation of said disk and the-successive filling and discharge of the water from said chambers, substantially as specified.

8. The radial plungers e,'connected in .pairs, as-described, and arranged 'to slide in chambers d, so as 'to be successively retracted to expel the water in their=respective chambers by the force of the water as it in's'uccession fills the empty chambers, and causing rotation by the preponderation thus produced, substantially as specified.

RICHARD J. ROGERS.
